This invention relates to a hydrorneter primarily designed for rn'easuring the meant of charge ofele'ctrici'ty in' a battery, but-it is tO'rbG understood that a hydroine'ter, accordance with this invention can be enr' ployed for any purposes for which it is applioable, and the invention has for its objectto provide, as hereinafter set forth, a device of the class referred to, a manner to prevent", when tilted in one direction, dropping acid or other liquid when the device is pulled away from the battery after being used.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a hydr'oineterincluding a transparent tube or j'ar'carrying the i'neter element and having means for establishing comniuniea= tion therebetween a battery and with the tube or jar further provided with a suction means for drawing therein the-liquid from the battery whereby the meter el'einent coacti'ng with the liquid will indicate the amount of the charge of electricity in the t ry a a.

A further object of the invention is to provide, in a 'niannei"ashereinafter set forth, a hydroineter including a transparent tube or for the meter element, and with the tube or jar construotedof glass and proyided with means at each end to permit of positioning therein andren 'oving therefrom the meter element, and further with said means acting to prevent breakage of the ends of the tube or jarby the iinpact of the rneter element,

Further objects of the invention are to provide, in a manner as hereinafter set forth, a hydroin'eter for the purpose referred to and which is simple its construction and arrangement, strong" dui'able, compact, thoroughly efficient in its use, convenientlyhandied, and comparativelyinexpensive to manufac ture. I

With the foregoing and other objects in view, the invention consists of the novel constructi'on, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings wherein sh'own' an efnbodirnent of the inv'ention but' it is to be understood that changeawariations and modifications can be resorted to'which fall within the scope or] the claimsh'eren'iito' appended. Y

iThe drawing" illustrates vertical section, ah'ydromfeter in accordance with this inv'entioi'i' and further the adaptation thereof constructed in i in connection with an electric ter'y,

Referring to the drawing 1 indicates the meter element, of known construction, and

storage bat which is provided with suitable graduations as indicated at 2, and 3 generally indicates a transparenttube 0r jar in which is arranged the meter element 1. i

The tubeir is constructed of glass, which 15 transparent and which is formed with a head portion 4,- a neck portion 5, a body portion 6, and a base portion 7. The head portion 4 is of spherical contour and pr0- v'ic'led with an opening 6 at its outer end and an opening 7 at its inner end. One side of the head 4 is also provided witlran opening -8. Formed integral; wit-lithe head,

4 and surrounding the o ening ,6 is an an-V n-ular flange 9, having a flaring inner face 10, and tightly engaging withthe inner face or the flange 9 is aresilient closure plug 11 which also actsas a cushion. tegra l the headt and having its-inner face registering with the wall of the open- 8, is a right angularly disposed tubuin extension 12 Tl'1'e' neck- 5 is of flaring Formed incontour and has its upper end merging into inner 'endof the head- 4' and the inner face of the neck!) is'flush with the Wall of opening 7' frirm'ed at the inner end of;

the head- 4, The 'bodyfportion termed of bulged contour, and gradually increases indiame't'er from eac lr'e'ndtowards the transverse center thereof. The body portion 6 merges into the inner end the neck 6, is what may be 5 and in the inner end of the base portion 7..

The major part of the body portion 6- is of greater diameter than the neck 5 and base portion 7 thereby increasing the capacity of the tube 3, than would be the case, if the tube was of the same-diameter throughout. v The inter'inediate part of the body portion 16 is of greater diameter than the headportion 4. The body portion 6 tapers from its transverse center towards each end thereof and is of curved contour in the direction of its lengthin longitudinal section.

The base portion? from its point of joind'er with the body portion 6, g radually increases in diameter for the major portion of its iengt hyand the outer terminal portion part of the base portion 7 is inturned as at '13. The" base'portion 7 is provided with an opening 14' at its outer end and formed inill) 'tegral with the base portion 7 is an annular flange having its inner face flush with the wall of the opening 1 1. The inner face of the flange 15 is tapered, as at 16 and of the opening 18.

The resilient plugs 11 and'17 provide a liquid tight joint at the ends of the tube 3 and further act to prevent the breakage of the ends of the tube 3, when impacted upon by the meter element 1. The meter element 1. preferably is inserted into the tube 3, by removing the plug 11, after which the latter is mounted in the flange 9. I

Connected with the tubular extension 12, is a f exible tubing 20 provided with a hollow spherical outer end 21, which constitutes a suction ball and the diameter of the latter is materially greater than the diameter of the tubing. 20. v Attached to the tubular extension 19 is a flexible tubing 22 for establishing communication between the liquid receiving chamber 23, formed by the tubing 3, and the battery 24.

Vfhen the ball 21 is compressed and expanded, the liquid 25, from the batter 24, will be drawn into the chamber 23 and which raises the meter element 1, and when the latter sinks to, the desired pointin the liquid 25, the level of the latter, associating with a graduation 2, will measure the amount of charge of electricity in a battery. Theangularly disposed tubular extension 12, 19 permit of a test being made without moving a battery from its cabinet or other container by simply removing the cap and inserting an extension in the battery. The tubular extension 12 makes it possible to complete the operation of reading without danger of having the meter element forced in the suction ball as often happens when the suction ball is above such element. A further advantage obtained by the angularly disposed tubular extensions is that the volume of air is equal to two-thirds the volume of the tube or jar making it impossible for any liquid to enter the suction ball. This consequently assures an accurate reading.

The shape of the portions 6 and 7 eliminates the danger of the meter element sticking to the sides of the tube or jar as such element cannot come in contact therewith. It is thought that the many advantages of a hydrometer, in accordance with this invention, can be readily understood, and although the preferred embodiment of the invention is'as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall within the scope of the invention as claimed.
